FILTER.

SPECIFICATION forming part of Letters Patent No. 609,754, dated August 23, 1898.

Application filed October 26, 1897. Serial No. 656,381. (No model.)

My invention relates to filters, and more particularly to filters of that class which are coupled onto pipes or faucets from which wa! ter is discharged under pressure; and it consists in certain novel and peculiar features of construction and combinations of parts hereinafter described and claimed.

The object of the invention is to produce a filter of this character which filters the water thoroughly and is of simple, strong, durable, and knockdown construction, to the end that the filtration cylinder may be easily and quickly removed, cleaned, and replaced'in its casement. 1

Other objects of the inventionwill hereinafter appear, and be pointed out inappen'ded claims. I

In the accompanying drawings, Figure 1 represents a central vertical section of a filter embodying my invention. Fig. 2 represents a top plan view of the same. Fig. 3 is a horizontal section taken on the line III III of Fig. 1. Fig. 4 is a horizontal section taken on the line IV IV of Fig. 1.

In the said drawings, 1 designates a vertical cylinder provided at its lower end with a screw threaded passage or opening 2,'mounted upon the upper end of an elbow 3, coupled in the customary manner to the discharge pipe (not shown) of a waterworks system, said pipe being provided with a valve 4 for controlling the passage of the water therethrough. The cylinder or casement is diametrically enlarged at its upper end, as shown at 5, and is pro vided externally with an annular horizontal flange 6. V

7 designates a packing-ring, of rubber or its equivalent, which depends into the enlargement of the cylinder or casement and is provided at its upper end with an outwardly prm jecting horizontal flange 8, which rests upon the flange 5 of the easement, but is provided in its outer edge at suitable intervals with notches for a purpose which will presently appear.

designates a clamp-ring which is of angular form incross-section and is clamped down upon the flange 8 of 'the packing-ring by means of a series'of screw-bolts 11, which extend up through the fiangeIG of the casement, the notches 9 of the packing-ring, and ,into threadedholes in said clamp-ring, as

shown clearlyin Fig. 1.

12 designates a clamp-plate provided with an upwardly-proj ecting annular wall 13 about equal in depth to the packing-ring and flaring upwardly and outwardly slightly by preference. Said plate is provided centrally at its upper side with an internally-threaded boss 14 and at its under side with a boss 15, which tapers at its lower end. The boss 15 is provided with radial passages 16 just below the plate and witlra vertical passage 17, which forms a channel for communication between the passages 16 and the hollow discharge-pipe 18, screwed down into the boss 14, and of approximately semicircular form at its upper end. The boss 15 is furthermore provided centrally with a recess in which fits snugly the upper end of a tie-rod 19, said rod being secured in such position by means of a cross-pin 20, asshown.

21 designates a washer, of rubber or equivalent material, which .is fitted at the bottom of the clamp-plate concentrically. of its con ter. Said packing-ring is of smaller diameter, preferably, than said clamp-plate, and is provided with a central opening 22, having a diameter somewhat larger than the boss 15, which it encircles.

23 designates the filtration stone or substance. It is of tubular form and is fitted endwise against the washer 21 and is of smaller diameter than the easement in order that an annular space or passage may be provided between the two. A packing-disk 24:, of rubber or equivalent material, fits squarely against the bottom of said filtration-cylinder and snugly upon the tie-rod depending aXially through it. A thin metallic'plate 25 upon said rod bears against the under or opposite side of said packing-disk and is clamped tightly against the same by means of a nut 26 upon the threaded end of said rod in order that by grasping and raising the gooseneck the filtration-cylinder may be lifted bodily out of the casement l and quickly cleansed by brushing or scrubbing the dirt from its outer surface in the customary manner.

By reference to Fig. 1 it will be noted that the tendency of the water impinging forcibly against the plate and packing-disk at the base of the cylinder would tend to lift the latter upwardly out of the casement. To prevent such action taking place I employ a latch-bar. 27, which is provided centrally with a hole 28, fitting loosely upon the tube or pipe 18 and of length to rest upon the horizontal portion of the angle clamp-ring 10, in order that under pivotal manipulation its ends may be caused to pass under the oppositely-disposed hooks 29, cast integral with said clamp-ring.

When the parts of the filter are assembled as shown and the water turned on, it is obvious that the latter as it passes up through the annular space surrounding the filtrationcylinder enters the enlargement of the easing externally of the packing-ring and there exerting an inward pressure forces the packing-ring 7 against the external surface of the flange 13 of the clamp-plate 12 so tightly that it is absolutely impossible for the water to pass up between said parts. It is obvious also that the water exerting such pressure cannot escape between the flange of the packing-ring and the upper end of the flange 6 of the casement, because the flange of said packing-ring is clamped down upon the flange 6 by means of the clamp-ring 10. As the water is thus confined it obviously must seep through the tubular filtration-cylinder for its full length and pass up through the channel of the same and'around the boss 15, (whose ends taper to afford as little obstruction as possible,) through the grooves 30, formed in the upper end of the cylinder to receive the projecting ends of the pin 20, and into the opening 22 of the Washer 21, from which chamber it passes freely, by way of the connecting passages 16 and 17, through the communicating discharge tube or pipe 18.

When it is desired to remove the filtrationcylinder to cleanse it, the latch-bar 27 is pivotally operated to disengage it from the hooks 29, and then by grasping the discharge-tube 18 the filtration-cylinder may be lifted bodily filtration-cylinder in said casement, a washer or packing ring provided with a central opening, clamped by said filtration-cylinder against the bottom of said clamp-plate, said washer-opening affording communication between the-channel of the filtration-cylinder and said discharge-pipe, and a packing-disk clamped up against the bottom of thefiltration-cylinder, substantially as described.

2. A filter, comprising a casement having an opening in its bottom to receive the unfiltered water and enlarged diametrically at its upper end, apacking-ring depending into the enlargement'of the cylinder and provided with a flange resting upon the upper end of the cylinder, and a ring clamped down upon the flange of saidpacking-ring, in combination with a clamp-plate provided with a wall externally and snugly embraced by said packing-ring, and provided also with a central passage and a discharge -pipe communicating therewith, a washer or packing-ring at the bottom of said plate and provided-with a central opening in communication with the central passage of the plate, a tubular filtrationstone having its channel in communication with the opening of said washer or packingring, and clamping said washer or ring firmly against the bottom of said plate, a packingdisk clamped against the lower end of said tubular filtration-stone, and a connection between said packing-disk and said clampingplate, to the end that the removal of the latter will insure the removal of the former and the-interposed stone, substantially as described.

3. A filter, comprising a casement having an opening in its bottom, to receive the unfiltered water, a flexible packin g-rin g clamped in the upper end of said casement, a clampplate embraced snugly by said packing-ring and provided with a discharge-tube, a tubular filtration cylinder in said casement, a washer or packing-ring provided with a central opening, clamped by said filtration-cylinder against the bottom of said clamp-plate, said washer-opening affording communication between the channel of the filtrationcylinder and said discharge-pipe, a packingring clamped up against the bottom of said filtration cylinder, and means to lock the clamp-plate and the connected parts in their operative positions within the casement, sub stantially as described.

4. A filter, comprising a casement having an opening in its bottom to receive the un filtered water, a flexible packing-ring in and upon the upper end of the casement, a clampring clamping said packing-ring down upon the easement, and provided at diametrically opposite points with oppositely disposed hooks, a clamp-plate embraced snuglyby said packing-ring and provided with a dischargetube,a tubular filtration-cylinder in said casement, a washer or packing-ring provided with a central opening, clamped by said filtrationcylinder against the bottomof said clamp filtration-cylinder, and a latch-bar pivotally mounted upon the discharge pipe of the clamp-plate and engaged at its ends by the hooks of the clamp-ring, substantially as de scribed.

5. A filter, comprising a casement having an opening in its bottom, aflexible packingring clamped in its upper end, a clamp-plate embraced externally and snugly by the packing-ring and provided with a central passage, a discharge-pipe communicating therewith, a boss depending centrally and provided with radial passages communicating with said central passages, a tie-rod connected to and depending from said boss, a washer at the bottom of the clamp-plate and provided with an opening through which said boss depends, a tubular filtration-stone surrounding said tierod and having its channel in communication with the opening of said washer and with the radial passages of said boss, a packing-disk at the bottom of said stone, and a nut clamping said disk against the bottom of said stone, and said stone against the washer at the bottom of the clamping-plate, substantially as and for the purpose described.

In testimony whereof I affix my signature in the presence of two witnesses.
